Beauregard Castle, Medieval castle ruins in Chippis, Switzerland

Beauregard Castle is a ruin on a rocky spur at the entrance to Val d'Anniviers, on the right bank of the Navizence at 1,012 m above Chippis. Its remains include a dwelling served by a spiral staircase, a tower of uncertain function and a circular cistern, all enclosed by a perimeter wall. A natural fault separates the spur from the path, which was crossed by a wooden footbridge in the Middle Ages.

The castle's origin is uncertain: it is documented only in 1457 as "bel regard" and in 1545 as "Perigard", and its style suggests a 12th-century build. It belonged to the Raron family before 1380. In 1387 troops of Amadeus VII damaged it and hanged Peter of Raron's sons at Sion; in 1416–1417 Valaisan communes besieged and burned it, and it was never rebuilt.

The castle is recorded in regional archives under two names: "bel regard" in a 1457 deed and "Perigard" on a 1545 map. Locals also call it "l'Imprenable" (the Impregnable), a nickname earned by its position above a natural fault that cut it off from the path.

The site is accessible from Niouc via a marked walking trail, and information panels with QR codes provide audio guide access. The exposed hilltop setting means weather can change quickly, so appropriate footwear and clothing are advisable.

Archaeological digs between 2008 and 2011 uncovered a circular water cistern and remnants of a spiral staircase inside the castle. These discoveries reveal details about how the fortress operated in medieval times.
